根因分析

尝试从 flask 导入 current_app，但它不是顶级导入；它是 flask.globals 的一部分。

English

Attempting to import current_app from flask, but it's not a top-level import; it's part of flask.globals.

generic

解决方案

  1. 90% 成功率 Import current_app from flask.globals. 
    from flask.globals import current_app
  2. 85% 成功率 Use app.app_context() to access current_app. 
    with app.app_context():
    from flask import current_app
    # use current_app

无效尝试

常见但无效的做法:

  1. Using 'from flask import current_app' incorrectly in a script. 70% 失败

    current_app is available only within a request context; importing it outside causes ImportError.

  2. Typo: using 'currentapp' instead of 'current_app'. 80% 失败

    The exact name is 'current_app'; any typo leads to ImportError.
